According to Kyodo News Agency on August 12, Kyodo News Agency learned from trade statistics on the 11th that Japan’s imports of nuclear fuel uranium and fuel assemblies for nuclear power plants in 2019 are almost zero. This may be the first time since imports began in the 1960s. The reason behind this is that under the influence of the new safety standards of Tokyo Electric Power Company after Fukushima nuclear accident, fuel manufacturing plants in Japan have been shut down and few nuclear power plants have been restarted. This symbolizes the stagnation of the nuclear power industry. < p > < p > natural uranium ore is refined, concentrated and processed into nuclear fuel, which is loaded into metal tube and used in nuclear power station in the state of fuel assembly. As there is no good deposit in China, Japan imports not only enriched uranium from overseas, but also natural uranium and aggregates. Donghai nuclear power plant in Donghai village, Ibaraki County, reached critical state for the first time as a commercial nuclear power plant in 1965, when finished fuel products were imported. After 1972, the classification of trade statistics has been changed, and the imports of enriched and natural uranium and aggregates can be obtained. In the case of an increase in the number of nuclear power plants in operation, there may also be exchange rate effects, reaching a maximum of 280.4 billion yen (about 18.4 billion yuan) in 1984. < / P > < p > for a period of time, the import value was maintained between 100 billion and 150 billion yen. In 2012, the second year of Fukushima nuclear accident, it was 82.7 billion yen, which continued to decrease under the influence of nuclear power plant outage in various regions, and dropped to 2.9 billion yen in 2016. After the restart of some nuclear power plants, it increased to nearly 50 billion yen in 2017 and 2018, but it was 45 million yen in 2019. According to the analysis, the nuclear power plant uses almost zero amount of nuclear fuel, which may be imported for experiments. Of the 54 nuclear reactors operated before Fukushima nuclear accident, 9 nuclear reactors meeting the new safety standards were restarted. However, four plants of three fuel manufacturing companies in Japan are under review of engineering plans based on the new standards and are now in shutdown. According to Kansai, Shikoku and Kyushu, the three power companies that have restarted the nuclear power plant, the nuclear power plant has ensured the fuel needed for its operation in a few years.
